</span>
當然,盡管說不能兼容,可是對於為什么不能兼容還是須要解釋一下的,其關鍵在於這么個選擇器的問題:input[type=radio]:before。:beofre這個偽類選擇器在主流瀏覽器中能夠在P,span,div等標簽插入一些式樣,可是在input中就不行,索性chrome支持這一特性,而本實例也正是環繞着一特性進行開發。
其它不多說,直接上代碼和截圖。
效果截圖:
HTML代碼:
<label for="test1">Test for test1 </label> <input class="radio" type="radio" ID="test1" name="test" value="test1"/> <label for="test2">Test for test2 </label> <input class="radio" type="radio" ID="test2" name="test" value="test2"/> <br> <br> <br> <label for="check1">check1</label> <input id="check1" name="check" value="check1" type="checkbox" class="checkbox"/> <label for="check2">check2</label> <input id="check2" name="check" value="check2" type="checkbox" class="checkbox"/> <label for="check3">check3</label> <input id="check3" name="check" value="check3" type="checkbox" class="checkbox"/> <label for="check4">check4</label> <input id="check4" name="check" value="check4" type="checkbox" class="checkbox"/>
然后再是CSS代碼:
input[type=radio]{ font-size:1em; visibility: hidden; position: relative; display: inline-block; width: 1em; height: 1em; } input[type=radio]:before{ font-size:1em; top:12%; display: inline-block; position: absolute; content:' '; visibility: visible; height: 1em; width: 1em; display: block; background: url("../img/no.png") no-repeat; background-size: 1em 1em; } input[type=radio]:checked:before{ font-size:1em; content:' '; visibility: visible; height: 1em; width: 1em; background: url("../img/yes.png") no-repeat; background-size: 1em 1em; } input[type=checkbox]{ font-size:1em; visibility: hidden; position: relative; display: inline-block; width: 1em; height: 1em; } input[type=checkbox]:before{ top:12%; display: inline-block; position: absolute; content:' '; visibility: visible; height: 1em; width: 1em; display: block; background: url("../img/checkbox_no.png") no-repeat; background-size: 1em 1em; } input[type=checkbox]:checked:before{ content:' '; visibility: visible; height: 1em; width: 1em; background: url("../img/checkbox.png") no-repeat; background-size: 1em 1em; }
